Variables in Macro's

Trying to use a variable in a macro for a healing alias so it grabs whatever I'm using from pack or cloak and drinks it.
I have the aliases, but this would be much faster.

Example: do get @flask from pack,open @flask,drink @flask,close @flask,put @flask in pack

Macros are sent to the command processor, so simply make a macro that calls the alias you already have.
